Aegis: Enabling DeepSeek Harness Agents to "Align with Baseline First, Act Second, and Conclude with Evidence"

Aegis (ganyuanran/aegis) is a DeepSeek Harness workflow plugin maintained by GanyuanRan, with over 1100 GitHub stars. It packages the principles of "baseline first, evidence verification, and drift checks" into an installable Method Pack: aligning project contracts and boundaries before changes, proving results with fresh evidence before completion, and taking a fast path for simple tasks. This article introduces its core capabilities, the installation and doctor verification steps in DSH via `dsh plugin --profile web add`, typical natural language triggering methods, as well as considerations such as Bundle and compatibility modes, and permission boundaries.
